CLEARWATER, Fla. — Last week, the Phillies coaching staff attended a meeting to learn more about Major League Baseball’s new replay system, which will be installed this season. Sandberg said though he is just formulating his strategy, he expects to be aggressive.

Under the new system, managers will have one challenge to use per game. If they win that challenge, they are awarded another one to use. But, after the sixth innings, all reviewable plays will be looked at by umpires, regardless of a manager challenge or not.

Thus, managers could be swayed to use the challenges loosely and early in games.

“It will be interesting to see some of the spring training games and practice that,” Sandberg said. “Let’s see if those numbers are right on the money, but then it comes down to a play in the first inning or third inning and you say, this is a big play, let’s challenge it. No question you use them. I’d say be aggressive and use them.”

Sandberg said the Phillies will have five televised games this spring in which the replay system will be tested. Under the initial format, teams will be able to have a coach watch replays in the press box and call down to the dugout with a recommended call. Tweaks could be made to the system over the course of the season. Sandberg is steadfast in his support of the system, saying while the game involves human error, if the evidence is available to overturn a big call, he’s all for it.

“We’ll see how things happen,” Sandberg said. “Some of it will be a test run and experience it and trial and error. It might take half a season to get some things ironed out. For the most part we want to go in ready to go and have my system and if needs to be fine tuned we’ll make that judgment.”
